Has anybody bought and tried DeWitt aluminum radiators ? The cost seems high but if they are as good as they say about cooling I may try them. They say that their radiator features two rows of one inch wide tubes and will provide 30% more cooling than an equal size four-row copper radiator. Any information on them would be great. Thanks . Steve

A friend had a 56 car and 56 big block truck both running hot in Texas weather. Installed Cold Case in both and fixed the problems.They are not cheap but great quality. Loy

Not familiar with DeWitt but there are many crossflow aluminum radiators out there with similar construction. As long as the fabricated tanks are fully tig welded they make a fine radiator that lasts a long time and cools extremely well if you use a quality fan setup too.

Most if not all of the custom radiators use cores from a limited number of sources.

Living in Texas I wouldn't buy any radiator unless it had 1.25" tubes.
My two row radiator with these spec'd tubes cools my 350 / 11:1 engine (aluminum heads) just fine.

It's all good. mostly
